The royal wedding of Catherine Middleton, now the Duchess of Cambridge, and Britain's Prince William was full of fashion surprises.

There was Catherine's dress, designed by Sarah Burton for Alexander McQueen; her 1936 Cartier tiara; Queen Elizabeth II in the brightest of yellows; the glorious hats in shapes and colors that would rival those on any "Star Wars" movie set. And then there was Catherine's sister, Pippa. The beautiful brunette may have stolen the show from her big sis, at least a little, in her stunning ivory satin cowl-neck dress, also designed by Burton.

If you didn't know who Pippa Middleton was before the wedding, you should now. She's always been quite stylish, but post-royal wedding, the world is taking notice.

The day after the wedding, Pippa was spotted leaving the Goring Hotel in London, where the Middleton family stayed the night before the big day. Looking chic as could be, Pippa left in a pair of white jeans, a cream-colored top, a royal blue tailored blazer from Zara and neutral flats.

Part of the Middleton sisters' allure is that everything about them, including their clothing, seems modest, accessible and down to earth. Pippa's blazer retails for $100, a pretty frugal find already.

But if you're looking for something even more affordable, there's a double-breasted Boonie blazer from J. Crew in dark navy for $79.99, Gibson one-button blazer from Nordstrom for $88, Ponte knit jacket in deep blue from J. Jill for $34.99, Casual linen jacket from Forever 21 for $24.80 or the Thatch palm blazer from Anthropologie for $88.

You can achieve this look with any light-colored, lightweight top, but Urban Outfitters has some great finds such as the Pins and Needles lace inset blouse for $59 or the Line & Dot ruffle-sleeve tie top for $19.99.

Pippa's white jeans are ideal for summer and a nod to the nautical when paired with her royal blue blazer. For a "wear anywhere" pair, get jegging ankle jeans from American Eagle for $19.99 or Always Skinny jeans from the Gap in white wash for $59.50.

Pippa's flats are sensible, and the neutral color is elegant and versatile. For a similar look, try the City flat in gold from the Gap for $39.95. Or go with embellished Round flats in pewter from Forever 21 for $17.80.
